No NIC Failure during wizard install if C9800 Cloud controller in VM

david101011 — Thu, 03 Aug 2023 21:13:06 GMT

I'm setting up a lab to do some research on the C9130AXI-B wireless access point. As I understand it, I cannot do anything with the AP without a wireless controller, so I'm now trying to install that.

I've downloaded C9800-CL-universalk9.17.09.03.iso from https://software.cisco.com/download/home/286322605/type/282046477/release/Cupertino-17.9.3 and am attempting to load it into a VM on a machine connected to the access point. I've been using https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-cl-wireless-controller-cloud/nb-06-cat9800-cl-wirel-cloud-dep-guide-cte-en.html to attempt to install it. I don't get very far.

After boot, it asks me if I want to configure a management port. No matter what I say, I get this message:

"There arent enough interfaces to configure the device management."

I attempt to hook in all the network interfaces I have on the box, but it doesn't seem to make much of a difference. Even if I eventually get to the IOS prompt, none of my bridged interfaces show up. Can anyone give me any clues on how to proceed?

- What do you mean by that , the VM/hypervisor solution should be 'standalone' and not depend on access points (you may want to elaborate)

This is a lab setup, so I'm just trying to get this single AP to work. I have the AP wired to a NIC on an ubuntu linux box (through a PoE injector). On that linux box I have virtualbox running (I've also tried with qemu), and I'm attempting to install and configure the wireless controller on that VM using C9800-CL-universalk9_vga.17.09.03.iso using a bridged ethernet device. As I understand it, that's the only way to be able to do anything with the C9130AXI, since it appears to be an expensive doorstop without wireless controller software.

Am I not understanding the setup correctly? How am I supposed to control this AP?

Thank you for your terse reply.

Do you mean to tell me that this expensive piece of hardware is completely useless by itself? There is absolutely nothing I can do to use it?

- If you connect it to a poe capable switch , then it can be used.

I'll see if I can find a PoE switch. In the meantime, I understand that a PoE injector might not be supported, but I _do_ see traffic on the other side, so it looks like the AP is trying to do something:

10:19:59.183929 IP (tos 0x0, ttl 250, id 22778, offset 0, flags [none], proto UDP (17), length 332) 0.0.0.0.bootpc > 255.255.255.255.bootps: [udp sum ok] BOOTP/DHCP, Request from 48:8b:0a:XX:XX:XX (oui Unknown), length 304, xid 0x6b2ad88d, Flags [Broadcast] (0x8000) Client-Ethernet-Address 48:8b:0a:XX:XX:XX (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x---------- DHCP-Message Option 53, length 1: Release Server-ID Option 54, length 4: 0.0.0.0 Client-ID Option 61, length 7: ether 48:8b:0a:XX:XX:XX Vendor-Class Option 60, length 16: "Cisco AP C9130AX" Parameter-Request Option 55, length 10: Subnet-Mask, Domain-Name, Default-Gateway, BR Hostname, Domain-Name-Server, LOG, MTU NTP, Vendor-Option

(this is the output of `tcpdump` on the interface on the linux side). So I have a feeling if I could just get the WLC software running, it could talk to the AP.

I would also like to point out that my original post was regarding the installation of the 9800-CL software on Linux KVM, as described in https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-cl-wireless-controller-cloud/nb-06-cat9800-cl-wirel-cloud-dep-guide-cte-en.html#Deployingthe9800CLonLinuxKVM , so I assume that this _is_ supported behavior.

- My bad a power injector will work , but the AP needs a switched network to the controller , connecting it directly to a NIC on Ubuntu will not work ; for the rest you will have to tweak and or adjust network settings on Linux KVM in order for the cloud controller to be able to find network interfaces :

So @david101011 - see the 9800-CL release notes for supported hypervisors and platforms - anything else is NOT supported as Marce has said.

For PoE you can use a PoE switch or power injector (802.3at/POE+).

You do not need a separate WLC - you can convert the AP to run Embedded Wireless Controller (EWC) on AP. This installs a cut-down version of the IOS-XE WLC image on the AP which then runs the WLC and AP processes separately on the AP. You need a DHCP server which can provide at least 2 IP addresses because the WLC and the AP both require an IP. Once you have it setup you can change to static IPs if required.

For the record, I was able to get it to at least talk to the WLC if I used the virtual bridge as the management interface, and a bridge to the physical card as the 2nd (PCI passthrough would not work for me). The command to create the image was something like:

sudo virt-install \ --virt-type=kvm \ --name C9800 \ --ram 16384 \ --vcpus=9 \ --hvm \ --cdrom=/path/to/C9800-CL-universalk9.17.09.03.iso \ --network bridge=virbr0,model=virtio \ --network bridge=br0,model=virtio \ --graphics vnc \ --disk path=/var/lib/libvirt/images/C9800.qcow2,size=8,bus=virtio,format=qcow2

I got pretty far with this. The WLC was able to see the device and talk to it. However, I hit the next brick wall when I'm unable to configure it because apparently version 8.10.130.0 is too old to be configured with anything. The AP console shows an "out of space" error:

I can't upgrade it either, because as I said before, I'm just a sole developer with no support contract.

I also can't load in the software for the EWC, presumably because of the same "out of space" problem. It goes through the TFTP step and fails after a while, just saying "Terminated, curl: (143) Error". No idea what to try next.

This is a known issue - which is why in the release notes https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-9/release-notes/rn-17-9-9800.html you'll see Upgrade Path for Deployments with 9130 or 9124! The AP must be upgraded first to 17.3.5 or later and then to 17.9.x. You'd be best upgrading the AP to 8.10.185.0 - 15.3(3)JK9 - before trying that though.

Which I cannot do without a service contract with Cisco, correct?

Thank you. I will go back to my client to tell them they have purchased a 1000 USD useless piece of plastic and recommend they avoid buying Cisco products again.

Well it's about buying the right product for the right solution and customer.
The 9130 is a very capable high end AP but customers which use the Cisco enterprise products (like the 9130 AP) will normally buy that together with a support contract for software updates and TAC support.

Customers looking for a single AP solution without any support or subscription are probably better placed looking at the Meraki Go range. https://www.meraki-go.com/products/wifi-access-points/
